Deep drawing parts/stretching product new mould assembly needs to be done after the completion of the loom, proofing, also is to make some products as samples to qc department to control the size of measurement, to see if qualified. After finish this step, mould will be production stage. And in the process of mold production is likely to appear all sorts of structure, design thinking. Such as tensile ( Deep) The causes of rupture: 1 & gt; 。 Deep drawing die of convex concave die gap is too small ( Including overall clearance and intensive migration of local clearance) 2在 。 Die without rounded corners roughness is too large, 3 & gt; 。 Stretch material quality, the plastic is not good, 4 & gt; 。 Deep drawing height more than material of plastic deformation limit ( Deep drawing number for a) 5比; 。 The second deep drawing materials did not reach the designated position, 6 & gt; 。 Press edge is not enough, after deep drawing edge zou or concave convex improvement countermeasures: 1 & gt; 。 Deep drawing die clearance of the intensive will nap to normal, 2 & gt; 。 According to the requirements of grinding to normal, 3 & gt; 。 If material super rules too much change, the other can increase die corresponding R Angle and brightness can be avoided, 4 & gt; 。 Deep drawing, can divide a few times 5 & gt; 。 Adjust the positioning to correct positioning, 6 & gt; 。 Concave and convex mold rubber board and play the elasticity, increase the blank-holder force 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
